摘　　要：天生桥水库是一座堵洞口成库的岩溶水库。通过比较,水库除险加固设计选择了结构简单、方案经济合理、技术可靠的溶洞内新建拱形堵体方案。本文论述了该工程岩桥稳定性和防渗效果的研究工作,分析总结区域复杂的岩溶水文地质特征和处理措施,对类似工程具有指导意义。Tianshengqiao Reservoir is a karst reservoir formed by blocking cave entrance. The plan of newly establishing arch-shaped closing body in karst cave is selected for reservoir risk removal and reinforcement. The plan is characterized by simple structure,economic and rational scheme and reliable technology. In the paper,the research on rock bridge stability and anti-seepage effect in the project is described. Complex karst hydro-geological characteristics and treatment measures in the region are analyzed and summarized,which have guidance significance for similar projects.
